PS Magazine, also known as
PS, The Preventive Maintenance Monthly, is an
official publication of the U.S. Army, providing information for all soldiers
assigned to combat and combat duties. The magazine covers issues
concerning maintenance, maintenance procedures and supply problems.
In 1968 and 1969, Eisner illustrated
The M16A1 Rifle (DA PAM 750-30) as a standalone issue of
PS specifically to address issues related to the then-new
M16 rifle as it was fielded in
Vietnam.
